Summary: chromatin in Brief
Chromatin [ˈkrəʊmətɪn] is the material of which the chromosomes of eukaryotic organisms are composed. It consists of protein, RNA, and DNA. Chromatin is responsible for storing genetic information and can be modified by various enzymes. It comes in two forms: heterochromatin, which is tightly packed and inaccessible for transcription, and euchromatin, which is loosely packed and accessible for transcription. Chromatin remodeling is the process by which the structure of chromatin is altered to allow access to DNA by transcription factors and other proteins.
